Description

Technical Field

[0001] This utility model relates to the field of coil guiding technology, specifically a coil guiding mechanism. Background Technology

[0002] Existing roll conveying mechanisms, where the roll material is not limited to film, require the film to be conveyed straight throughout the mechanical movement during the film feeding process. The top and bottom films are adhered with adhesive backing. Once wrinkles appear, the film is prone to jamming or breaking between the guide rollers and pressure rollers, causing equipment downtime and requiring manual film replacement or readjustment, which affects the efficiency of equipment use. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a roll material guiding mechanism.

The top film recovery roller is used to recover the top film of the roll material on the unwinding roller, and the bottom film of the roll material on the unwinding roller is recovered by the bottom film recovery roller after passing through the vacuum adsorption platform. The roll material on the unwinding roller has multiple equally spaced positioning holes on both sides, and the upper surface of the vacuum adsorption platform has multiple positioning pins that cooperate with the multiple positioning holes.

[0010] As a preferred embodiment of this utility model, the spacing between adjacent positioning holes is 5 mm to 30 mm.

[0011] As a preferred embodiment of this utility model, the upper part of the positioning pin is provided with a guide portion with a gradually decreasing diameter.

[0013] As a preferred technical solution of this utility model, the frame is provided with a tensioning wheel for tensioning the bottom film between the vacuum adsorption stage and the bottom film recovery wheel.

[0014] As a preferred embodiment of this utility model, the positioning pin is integrally formed with the upper surface of the vacuum adsorption stage, and the surface of the positioning pin is a smooth mirror surface.

[0015] The beneficial effects of this utility model are:

[0016] This type of roll guiding mechanism has multiple equally spaced positioning holes on both sides of the roll, and multiple positioning pins on the upper surface of the vacuum adsorption table that cooperate with the multiple positioning holes. The positioning holes on both sides and the positioning pins of the vacuum adsorption table guide the roll, ensuring that the film forms a fixed trajectory after entering the vacuum adsorption table.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Example: Figure 1 , Figure 2 , Figure 3 As shown, this utility model discloses a roll material guiding mechanism, which includes a frame 1. The frame 1 is equipped with a roll material unwinding roller 2, a top film recovery roller 3, a vacuum adsorption platform 4, and a bottom film recovery roller 5. The roll material 11 includes a top film 12, a bottom film 13, and a product 14 located between the top film 12 and the bottom film 13. The top film recovery roller 3 is used to recover the top film 12 of the roll material 11 on the roll material unwinding roller 2, and the bottom film 13 of the roll material 11 on the roll material unwinding roller 2 is recovered by the bottom film recovery roller 5 after passing over the vacuum adsorption platform 4. The roll material 11 on the roll material unwinding roller 2 has multiple equally spaced positioning holes 6 on both sides, and the upper surface of the vacuum adsorption platform 4 has multiple positioning pins 7 that cooperate with the multiple positioning holes 6. Multiple positioning holes 6 are provided on both sides of the roll 11 at equal intervals, and multiple positioning pins 7 are provided on the upper surface of the vacuum adsorption platform 4 to cooperate with the multiple positioning holes 6. The positioning holes 6 on both sides and the positioning pins 7 of the vacuum adsorption platform 4 are used for guidance to ensure that the film forms a fixed trajectory after entering the adsorption positioning platform, which solves the problems of film deviation and wrinkling during the conveying process, and has the advantage of simple structure.

[0024] In one embodiment, multiple positioning pins 7 are arranged in a straight line along the movement direction of the roll 11 to ensure that the film forms a fixed trajectory after entering the vacuum adsorption stage 4, thereby solving the problems of film misalignment and wrinkling during the conveying process, and also having the advantage of simple structure.

[0025] In one embodiment, the height h of the positioning pin 7 is 1.8 mm to 2.2 mm, which facilitates the movement of the membrane.

[0026] In one embodiment, the diameter D2 of the positioning hole 6 is larger than the diameter D1 of the positioning pin 7. The diameter D2 of the positioning hole 6 is 2.1 mm, and the diameter D1 of the positioning pin 7 is 2 mm. This makes it convenient for the positioning pin 7 to be engaged in the positioning hole 6 during the movement of the membrane.

[0027] In one embodiment, the spacing between adjacent positioning holes 6 is 5 mm to 30 mm, wherein the specific spacing between adjacent positioning holes 6 can be set according to the conveying requirements of the roll 11. The upper part of the positioning pin 7 is provided with a guide portion 8 with a gradually decreasing diameter, facilitating the engagement of the positioning pin 7 into the positioning hole 6 during film movement. A guide wheel 9 is provided between the roll unwinding roller 2, the top film recovery roller 3, and the vacuum adsorption table 4, thus providing guidance and facilitating film movement. The frame 1 is provided with a tensioning roller 10 for tensioning the bottom film between the vacuum adsorption table 4 and the bottom film recovery roller 5, ensuring good tension. The positioning pin 7 is integrally formed with the upper surface of the vacuum adsorption table 4, and the surface of the positioning pin 7 is a smooth mirror finish, facilitating film movement and preventing scratches on the film.

[0028] For example, roll 11 can be double-sided adhesive-backed incoming tape (pressure swing adsorption incoming tape, PSA incoming tape). During operation, the roll 11 is manually loaded onto the unwinding roller 2 and manually pulled by the guide roller 9 to the top film recovery roller 3 and the bottom film recovery roller 5. After the positioning and tension are adjusted, the equipment is started. The top film 12 is driven by the guide roller 9 to the top film recovery roller 3 for recovery, and the bottom film 13 enters the upper surface of the vacuum adsorption table 4 through the guide roller 9. During the conveying process, the film is guided by vacuum adsorption, as well as by the positioning hole 6 and the positioning pin 7 of the vacuum adsorption table 4, ensuring the flatness of the film and limiting its movement. This solves the problems of film wrinkling and deviation that cause film jamming and breakage. When the bottom film 13 reaches the peeling position, the bottom film 13 makes a folding motion at the blade position at an angle of 30° while the peeling mechanism 15 is pushing and reciprocating. At this time, the product 14 is separated from the bottom film 13, and the suction head picks up the product 14 to the next process, realizing the key process of this equipment. After the product 14 is peeled off, the bottom film 13 is recycled under the traction of the bottom film recycling wheel 5, and the entire process ends.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
